Description

Technical Field

[0001] The utility model belongs to the technical field of oxygen concentrators, in particular to a humidifying cup which is easy to replace and is used for an oxygen concentrator. Background Art

[0002] At present, most oxygen concentrators use pressure swing adsorption air separation oxygen production technology (PSA), which uses air as raw material to separate and produce oxygen. The produced oxygen is relatively dry, so oxygen concentrators are equipped with humidification bottles to humidify the produced oxygen to improve the comfort of oxygen inhalation for users. During the use of the humidification bottle, the humidification cup needs to be repeatedly disassembled and assembled to change the water. However, the humidification cup of the household oxygen concentrators on the market is very troublesome to remove and install when changing the water.

[0003] Chinese utility model CN214860337U discloses a rotating bracket for a humidifier cup of an oxygen concentrator. Rotating brackets are arranged at both ends of a cup seat of the humidifier cup, so that the humidifier cup can rotate. When disassembling the humidifier cup, the cup body can be grasped and rotated in a direction away from the oxygen concentrator to disconnect the cup body from the internal pipeline of the oxygen concentrator, and then the cup body and the cup seat can be separated by pulling upward, so that the humidifier cup can be easily removed. When installing the humidifier cup, the bottom of the cup body is inserted into the cup seat, and then rotated in the direction of the oxygen concentrator to connect the cup body with the internal pipeline of the oxygen concentrator. The rotatable bracket makes it easy to disassemble and assemble the cup body and to replace the liquid in the cup body.

[0004] Although the above structure can solve the problem of replacing the existing humidification cup to a certain extent, its structure is too complicated. For the humidification cup body, the overly complicated structure will increase the cost of the humidification cup. In addition, the complicated structure will cause the humidification cup to have limitations and cannot be applied to different oxygen generators. Utility Model Content
